Like a boor (7)
I believe the answer is:
loutish
'like a boor' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for loutish that I've seen before include "Ill-mannered and coarse, behaviour say" , "like a hooligan" , "uncouth and aggressive" , "Boorish" .)
